I'm trying to build a chrome extension that updates its badge every time some event happens on my server- in this case, my server is receiving a webhook from Zoom and then informing my chrome extension that the event occurred. From there my chrome extension will update a counter on its' badge, to show that the event occured. I'm trying to build it according to the chrome extension Manifest V3 but I can't find any info on how to do this correctly.
To my understanding, in Manifest V3 all client-side scripts must run in a service worker. That service worker starts up, runs some code, and then shuts down again. I was planning to open a websocket in my background script, which would have been fine under manifest v2, but I don't think you can do that any more.
My question is: How do I maintain a connection to receive data in my chrome extension? When I say data in this case I really just mean an event informing my chrome extension to update the counter on its badge.
Are there other routes besides keeping a websocket open in the background? I've looked around at things like Google Cloud Messaging but I don't think that was intended for what I would like to use it for.
